Westwood, 22, was 4-1 with a 3.75 ERA over 15 appearances as a senior at the University of North Florida. He’s headed to short-season Class A Tri-City, joining Ramsay.

“Westwood’s an extreme strike thrower with a power fastball/slider combo,” Astros scouting director Mike Elias said. “Up to 95 mph and rolls a lot of groundballs. He can start or relieve, and our scouts see him in bullpen at major league level.”

Kessay, 19, was 8-2 with a 1.71 ERA as a sophomore at Scottsdale, Ariz., Community College. He struck out 98, gave up 58 hits and walked only 31 over 79 innings. He’s headed to short-season Class A Greenville.

“Kessay’s a tall lefty with starting pitcher profile and three-pitch mix,” Elias said. “One of top strikeout pitchers in his Junior College conference and a competitor.”

Booth, 22, hit .290 with six home runs and 38 RBIs as a senior at the University of Alabama. He’ll report to the Gulf Coast League Astros.

“Booth’s a veteran college catcher with a very accurate arm and good approach at the plate,” Elias said. “He led Alabama in average and on-base percentage, and he’s a team-leader type catcher.”
